Prisons are facilities where people who have committed crimes are held as a form of punishment. They are designed to keep society safe by isolating individuals who break the law. In prisons, inmates may have limited freedom and must follow strict rules. The goal is often to rehabilitate them so they can reintegrate into society after serving their time. Inside prisons, inmates may participate in various programs, such as education and job training, to help them develop skills for life after release. Guards and staff work to maintain order and ensure the safety of everyone inside. Prisons can vary in security levels, from low-security facilities to high-security ones for dangerous offenders.
